Street address regex PHP
Usually, it’s a bad idea to validate street addresses using regular expressions (read below). But in some cases it might make sense and here’s a regular expression that can help with that
Simple address regex
Below is a regex that check for a pattern: Addr# Street Name, City, State ZIP code
"/^(\\d{1,}) [a-zA-Z0-9\\s]+(\\,)? [a-zA-Z]+(\\,)? [A-Z]{2} [0-9]{5,6}$/"
Enter a text in the input above to see the result
Example code in PHP:
// Validate street address
$street_address_validation_regex = "/^(\\d{1,}) [a-zA-Z0-9\\s]+(\\,)? [a-zA-Z]+(\\,)? [A-Z]{2} [0-9]{5,6}$/";
echo preg_match($street_address_validation_regex, '3344 W Alameda Avenue, Lakewood, CO 80222'); // returns 1
Notes on street address regex validation
Validating an address with a regex is usually a bad idea because of the way how address is written in different parts of the world. Usually, it’s better to just check that the address is not empty and let the user enter what do they want. Another way would be to use a third-party library like Google Places API which will convert information a user entered in a unique ID that would identify that address.
